Description

本発明は、外部導体の接近又は接触を検出するためのタッチパネルセンサ及びタッチ位置検出機能付き表示装置に関する。 The present invention relates to a touch panel sensor for detecting the approach or contact of an external conductor and a display device with a touch position detection function.

今日、液晶ディスプレイや有機ＥＬディスプレイ等の表示装置が組み込まれた種々の装置等（例えば、券売機、ＡＴＭ装置、携帯電話、ゲーム機）に対する入力手段として、タッチパネル装置が広く用いられている。タッチパネル装置は、基材と、基材上に設けられ、指などの外部導体の接近又は接触を検出するセンサ部と、センサ部に接続された配線と、を備えるタッチパネルセンサを含む。タッチパネルセンサの基材は、外部導体が検出され得る領域に対応するアクティブエリアと、アクティブエリアの周辺に位置する非アクティブエリアと、に区画される。タッチパネルセンサが表示装置の表示面に重ねられる場合、アクティブエリアは、表示装置から放出される映像光が適切に透過できるように構成される。 2. Description of the Related Art Today, touch panel devices are widely used as input means for various devices including a display device such as a liquid crystal display and an organic EL display (for example, ticket machines, ATM devices, mobile phones, game machines). The touch panel device includes a touch panel sensor that includes a base material, a sensor unit that is provided on the base material and detects the approach or contact of an external conductor such as a finger, and wiring connected to the sensor unit. The base material of the touch panel sensor is divided into an active area corresponding to a region where an external conductor can be detected, and an inactive area located around the active area. When the touch panel sensor is overlaid on the display surface of the display device, the active area is configured so that video light emitted from the display device can be appropriately transmitted.

タッチパネルセンサの構造として、基材の片側にセンサ部及び配線を設ける構造が知られている。例えば特許文献１において、タッチパネルセンサは、駆動電極及び検出電極を有し、基材の片側に二次元配列された複数のセンサ部と、駆動電極に接続されたドライブ線と、検出電極に接続されたセンス線と、を備える。この場合、駆動電極と検出電極との間に形成される電気力線が、外部導体の接近又は接触による影響を受けることに基づいて、外部導体の位置を検出することができる。 As a structure of a touch panel sensor, a structure in which a sensor unit and wiring are provided on one side of a base material is known. For example, in Patent Document 1, a touch panel sensor has a drive electrode and a detection electrode, and is connected to a plurality of sensor units that are two-dimensionally arranged on one side of a substrate, a drive line connected to the drive electrode, and a detection electrode. Sense lines. In this case, the position of the outer conductor can be detected based on the influence of the electric lines of force formed between the drive electrode and the detection electrode due to the approach or contact of the outer conductor.

特許文献１に記載のタッチパネルセンサの各センサ部において、駆動電極と検出電極とは、端部においてのみ互いに対向している。この場合、駆動電極と検出電極とによって形成されるコンデンサの静電容量を増加させるためには、駆動電極及び検出電極の端部の長さを増加させる必要がある。しかしながら、駆動電極及び検出電極の端部の長さを増加させると、各センサ部の寸法が増加し、この結果、タッチパネルセンサの分解能が低下してしまう。 In each sensor part of the touch panel sensor described in Patent Document 1, the drive electrode and the detection electrode face each other only at the end part. In this case, in order to increase the capacitance of the capacitor formed by the drive electrode and the detection electrode, it is necessary to increase the lengths of the end portions of the drive electrode and the detection electrode. However, when the lengths of the end portions of the drive electrode and the detection electrode are increased, the dimensions of each sensor unit are increased, and as a result, the resolution of the touch panel sensor is lowered.

タッチパネルセンサ
次に図１及び図２を参照して、タッチパネルセンサ２０について説明する。図２は、表示装置１５側から見た場合のタッチパネルセンサ２０を示す平面図である。タッチパネルセンサ２０は、相互容量方式のタッチパネルセンサとして構成されている。 Touch Panel Sensor Next, the touch panel sensor 20 will be described with reference to FIGS. 1 and 2.

The base material 22 includes a rectangular active area Aa1 corresponding to a region where an external conductor can be detected, and a rectangular frame-shaped inactive area Aa2 located around the active area Aa1. As shown in FIG. 2, the touch panel sensor 20 includes a plurality of sensor units 24, a plurality of first wires 26, a plurality of second wires 28, a plurality of first frame wires 27, and a plurality of second frame wires 29. Prepare. The sensor unit 24, the first wiring 26, and the second wiring 28 are disposed in the active area Aa 1 of the base material 22. On the other hand, the first frame wiring 27 and the second frame wiring 29 are arranged in the inactive area Aa2 of the base material 22. Each first wiring 26 is connected to a corresponding first frame wiring 27, and each second wiring 28 is connected to a corresponding second frame wiring 29. Further, the sensor unit 24, the first wiring 26, the second wiring 28, the first frame wiring 27, and the second frame wiring 29 are all provided on the first surface 22a side of the base material 22, but the present invention is not limited thereto. Instead, it may be provided on the second surface 22 b of the substrate 22.

（基材）
基材２２を構成する材料としては、例えば、ポリエチレンテレフタレート（ＰＥＴ）、シクロオレフィンポリマー（ＣＯＰ）などの有機材料や、ガラスなどの無機材料など、十分な透光性を有する材料が用いられる。基材２２が例えばＰＥＴなどの有機材料を含む場合、基材２２の厚みは例えば３０μｍ以上且つ２００μｍ以下であり、好ましくは３０μｍ以上且つ１００μｍ以下である。なお、センサ部２４、第１配線２６、第２配線２８、第１額縁配線２７及び第２額縁配線２９を適切に保持することができる限りにおいて、基材２２の具体的な構成が特に限られることはない。例えば、基材２２は、ＰＥＴフィルムの表面に設けられたハードコート層を更に含んでいてもよい。 (Base material)
As a material constituting the base material 22, for example, a material having sufficient translucency such as an organic material such as polyethylene terephthalate (PET) or cycloolefin polymer (COP) or an inorganic material such as glass is used. When the base material 22 contains organic materials, such as PET, the thickness of the base material 22 is 30 micrometers or more and 200 micrometers or less, for example, Preferably they are 30 micrometers or more and 100 micrometers or less. In addition, as long as the sensor part 24, the 1st wiring 26, the 2nd wiring 28, the 1st frame wiring 27, and the 2nd frame wiring 29 can be hold | maintained appropriately, the specific structure of the base material 22 is especially limited. There is nothing. For example, the base material 22 may further include a hard coat layer provided on the surface of the PET film.

（センサ部）
図２に示すように、複数のセンサ部２４は、基材２２の第１面２２ａ上に二次元配列されている。例えば、複数のセンサ部２４は、第３方向Ｄ３及び第３方向Ｄ３に交差する第４方向Ｄ４に沿って並んでいる。図２に示す例において、第４方向Ｄ４は第３方向Ｄ３に直交している。以下の説明において、第３方向Ｄ３においてｍ番目に位置し、且つ第４方向Ｄ４においてｎ番目に位置するセンサ部２４のことを、センサ部２４＿ｍｎとも称する。ｍ及びｎは任意の正の整数である。 (Sensor part)
As shown in FIG. 2, the plurality of sensor units 24 are two-dimensionally arranged on the first surface 22 a of the base material 22. For example, the plurality of sensor units 24 are arranged along the fourth direction D4 that intersects the third direction D3 and the third direction D3. In the example shown in FIG. 2, the fourth direction D4 is orthogonal to the third direction D3. In the following description, the sensor unit 24 located at the m-th position in the third direction D3 and at the n-th position in the fourth direction D4 is also referred to as a sensor portion 24_mn. m and n are arbitrary positive integers.

図３は、図２に示すタッチパネルセンサ２０の複数のセンサ部２４の一部を、例えばセンサ部２４＿１１、センサ部２４＿２１、センサ部２４＿１２及びセンサ部２４＿２２を拡大して示す平面図である。センサ部２４は、互いに対向する第１電極３０及び第２電極４０を有する。第１電極３０及び第２電極４０の一方は、信号電圧が印加される駆動電極として機能し、他方は、検出電極として機能する。例えば、第１電極３０が駆動電極である場合、第２電極４０が検出電極として機能する。この場合、第２電極４０には、第１電極３０と第２電極４０との間に形成されるコンデンサを介した容量結合によって、第１電極３０からの信号電圧が伝達される。 FIG. 3 is an enlarged plan view showing a part of the plurality of sensor units 24 of the touch panel sensor 20 shown in FIG. 2, for example, the sensor unit 24_11, the sensor unit 24_21, the sensor unit 24_12, and the sensor unit 24_22. The sensor unit 24 includes a first electrode 30 and a second electrode 40 that face each other. One of the first electrode 30 and the second electrode 40 functions as a drive electrode to which a signal voltage is applied, and the other functions as a detection electrode. For example, when the first electrode 30 is a drive electrode, the second electrode 40 functions as a detection electrode. In this case, the signal voltage from the first electrode 30 is transmitted to the second electrode 40 by capacitive coupling via a capacitor formed between the first electrode 30 and the second electrode 40.

第１電極３０は、複数の第１線状部分３１と、複数の第１線状部分３１に接続された第１接続部分３２と、を含む。複数の第１線状部分３１は、第１方向Ｄ１に延び、且つ第１方向Ｄ１に交差する第２方向Ｄ２に並んでいる。各第１線状部分３１は、第１方向Ｄ１に延びる一対の側部３１１を含んでいる。第１接続部分３２は、第１方向Ｄ１の一方の側（図３の例では上側）において複数の第１線状部分３１に接続されている。また、第１接続部分３２は、第２方向Ｄ２に延びている。第１接続部分３２は、第２方向Ｄ２に延びる一対の側部３２１を含んでいる。図３に示す例において、第２方向Ｄ２は第１方向Ｄ１に直交している。また、第１方向Ｄ１は上述の第３方向Ｄ３に平行であり、第２方向Ｄ２は上述の第４方向Ｄ４に平行である。 The first electrode 30 includes a plurality of first linear portions 31 and a first connection portion 32 connected to the plurality of first linear portions 31. The plurality of first linear portions 31 extend in the first direction D1 and are arranged in a second direction D2 that intersects the first direction D1. Each first linear portion 31 includes a pair of side portions 311 extending in the first direction D1. The first connection portion 32 is connected to the plurality of first linear portions 31 on one side in the first direction D1 (upper side in the example of FIG. 3). The first connection portion 32 extends in the second direction D2. The first connection portion 32 includes a pair of side portions 321 extending in the second direction D2. In the example shown in FIG. 3, the second direction D2 is orthogonal to the first direction D1. The first direction D1 is parallel to the third direction D3, and the second direction D2 is parallel to the fourth direction D4.

第１電極３０と同様に、第２電極４０も、複数の第２線状部分４１と、複数の第２線状部分４１に接続された第２接続部分４２と、を含む。複数の第２線状部分４１は、第１方向Ｄ１に延び、且つ第１方向Ｄ１に交差する第２方向Ｄ２に並んでいる。各第２線状部分４１は、第１方向Ｄ１に延びる一対の側部４１１を含んでいる。また、第２線状部分４１は、隣り合う２つの第１線状部分３１の間に位置している。例えば、第１線状部分３１及び第２線状部分４１は、第２方向Ｄ２に沿って交互に並んでいる。図３に示す例においては、同数の第１線状部分３１及び第２線状部分４１が交互に並んでいる。第２接続部分４２は、第１方向Ｄ１の他方の側（図３の例では下側）において複数の第２線状部分４２に接続されている。また、第２接続部分４２は、第２方向Ｄ２に延びている。第２接続部分４２は、第２方向Ｄ２に延びる一対の側部４２１を含んでいる。 Similar to the first electrode 30, the second electrode 40 also includes a plurality of second linear portions 41 and a second connection portion 42 connected to the plurality of second linear portions 41. The plurality of second linear portions 41 extend in the first direction D1 and are arranged in a second direction D2 that intersects the first direction D1. Each second linear portion 41 includes a pair of side portions 411 extending in the first direction D1. The second linear portion 41 is located between the two adjacent first linear portions 31. For example, the first linear portions 31 and the second linear portions 41 are alternately arranged along the second direction D2. In the example shown in FIG. 3, the same number of first linear portions 31 and second linear portions 41 are alternately arranged. The second connection portion 42 is connected to the plurality of second linear portions 42 on the other side in the first direction D1 (lower side in the example of FIG. 3). Further, the second connection portion 42 extends in the second direction D2. The second connection portion 42 includes a pair of side portions 421 extending in the second direction D2.

図３に示すように、各第１線状部分３１の側部３１１は、各第２線状部分４１の側部４１１に対向している。この場合、第１線状部分３１の側部３１１と第２線状部分４１の側部４１１との間には、側部３１１及び側部４１１の対向部分の長さに比例した静電容量を有するコンデンサが形成される。従って、第１電極３０と第２電極４０との間には、第１線状部分３１及び第２線状部分４１の数、並びに側部３１１及び側部４１１の対向部分の長さに比例した静電容量を有するコンデンサが形成される。このため、上述の特許文献１のように駆動電極及び検出電極の端部でのみ互いに対向する場合に比べて、静電容量を増加させることができる。このことにより、センサ部２４の検出感度を高めることができる。 As shown in FIG. 3, the side portion 311 of each first linear portion 31 faces the side portion 411 of each second linear portion 41. In this case, a capacitance proportional to the length of the side portion 311 and the opposing portion of the side portion 411 is provided between the side portion 311 of the first linear portion 31 and the side portion 411 of the second linear portion 41. A capacitor is formed. Therefore, the distance between the first electrode 30 and the second electrode 40 is proportional to the number of the first linear portions 31 and the second linear portions 41 and the lengths of the opposing portions of the side portions 311 and the side portions 411. A capacitor having a capacitance is formed. For this reason, compared with the above-mentioned patent document 1, compared with the case where it opposes only at the edge part of a drive electrode and a detection electrode, an electrostatic capacitance can be increased. As a result, the detection sensitivity of the sensor unit 24 can be increased.

It extends along the straight line. In the example illustrated in FIG. 5, the fifth direction D5 and the sixth direction D6 each form a predetermined angle, for example, 45 °, with respect to the first direction D1. In this case, a square opening 62 is defined between the conductive wires 61. The size of the opening 62 is such that the ratio of the area occupied by the opening 62 (hereinafter referred to as the opening ratio) in the area of the active area Aa1 is sufficiently high, so that the image light from the display device 15 is appropriate. It is set so that the active area Aa1 can be transmitted with the transmittance. The direction in which the conducting wire 61 extends and the shape of the opening 62 are not particularly limited.

図４及び図５において、一点鎖線は、第１線状部分３１などのセンサ部２４の構成要素の輪郭を示すために仮想的に描いた線である。センサ部２４の各構成要素の輪郭は、導線６１の端部を連結した線によって画定される。例えば図５に示すように、第１線状部分３１の側部３１１の輪郭は、第１方向Ｄ１に沿って並ぶ複数の導線６１の端部を連結した線によって画定される。 4 and 5, the alternate long and short dash line is a line drawn virtually to show the outline of the constituent elements of the sensor unit 24 such as the first linear portion 31. The outline of each component of the sensor unit 24 is defined by a line connecting the ends of the conducting wire 61. For example, as shown in FIG. 5, the outline of the side portion 311 of the first linear portion 31 is defined by a line connecting ends of a plurality of conductive wires 61 arranged along the first direction D1.

図４及び図５において、符号Ｓ１は、第１方向Ｄ１に沿って延びる隙間（以下、第１隙間とも称する）を表し、符号Ｓ２は、第２方向Ｄ２に沿って延びる隙間（以下、第２隙間とも称する）を表す。図４及び図５に示す例において、第１隙間Ｓ１は、第１線状部分３１の側部３１１と第２線状部分４１の側部４１１との間に形成される。また、第２隙間Ｓ２は、第１線状部分３１の端部３１２と第２接続部分４２の側部４２１との間、又は第２線状部分４１の端部４１２と第１接続部分３２の側部３２１との間に形成される。好ましくは、導線６１は、隙間Ｓ１、Ｓ２を挟んで隣接する導線６１の一方を延長すると他方に重なるよう、配置されている。例えば、隙間Ｓ１、Ｓ２は、直線状に延びる１本の導線６１のうち隙間Ｓ１、Ｓ２となるべき領域に位置する部分を、図５に点線で示す分断部６３として除去することによって、構成されている。これによって、隙間Ｓ１、Ｓ２が目立つことを抑制することができる。 4 and 5, reference numeral S1 represents a gap extending along the first direction D1 (hereinafter also referred to as a first gap), and reference numeral S2 is a gap extending along the second direction D2 (hereinafter referred to as a second gap).

It is formed between the side portion 321. Preferably, the conducting wire 61 is disposed so as to overlap with the other when one of the neighboring conducting wires 61 is extended with the gaps S1 and S2 interposed therebetween. For example, the gaps S1 and S2 are configured by removing a portion located in an area where the gaps S1 and S2 are to be formed as a dividing portion 63 indicated by a dotted line in FIG. ing. Thus, the conspicuous gaps S1 and S2 can be suppressed.

In this case, even if one intersection 61a is removed due to an etching defect or the like during manufacturing, at least one intersection 61a remains in the first linear portion 31 and the second linear portion 41. be able to. Therefore, a current can be passed through the first linear portion 31 and the second linear portion 41 along the first direction D1 by using at least one remaining intersection 61a. Thereby, the possibility that the first linear portion 31 and the second linear portion 41 are disconnected can be reduced.

The distance e between and can also be enlarged.

図１０及び図１１は、第１線状部分３１と第２線状部分４１との間の間隔ｃ、第１配線２６と第２線状部分４１ａとの間の間隔ｄ、及び、第２配線２８と第１線状部分３１ｂとの間の間隔ｅを拡大することによって実現される効果を説明するための図である。図１０は、第３線状部分５１が存在しない場合のセンサ部２４の一例を示す断面図であり、図１１は、第３線状部分５１が存在する場合のセンサ部２４の一例を示す断面図である。 10 and 11 show the distance c between the first linear portion 31 and the second linear portion 41, the distance d between the first wiring 26 and the second linear portion 41a, and the second wiring. It is a figure for demonstrating the effect implement | achieved by enlarging the space | interval e between 28 and the 1st linear part 31b. 10 is a cross-sectional view illustrating an example of the sensor unit 24 when the third linear portion 51 is not present, and FIG. 11 is a cross-sectional view illustrating an example of the sensor unit 24 when the third linear portion 51 is present. FIG.

図１０及び図１１において、符号７１は、第１線状部分３１と第２線状部分４１、及び、第１配線２６と当該第１配線２６と隣り合う第２線状部分４１ａとの間に形成される電気力線を表す。電気力線７１は、第１線状部分３１と第２線状部分４１との間の間隔ｃ、第１配線２６と第２線状部分４１ａとの間の間隔ｄ、及び、第２配線２８と第１線状部分３１ｂとの間の間隔ｅが大きいほど、広域にわたって広がる。電気力線７１が広がる範囲が大きいほど、センサ部２４や、センサ部２４と第１配線２６または第２配線２８とが外部導体７２を検出可能な範囲も広くなる。例えば、センサ部２４が外部導体７２を検出し始める際の、基材２２の第２面２２ｂと外部導体７２との間の距離Ｅが大きくなる。すなわち、センサ部２４の感度が向上する。 10 and 11, reference numeral 71 denotes between the first linear portion 31 and the second linear portion 41, and between the first wiring 26 and the second linear portion 41 a adjacent to the first wiring 26. It represents the electric lines of force that are formed. The electric lines of force 71 are the distance c between the first linear portion 31 and the second linear portion 41, the distance d between the first wiring 26 and the second linear portion 41a, and the second wiring 28. And the first linear portion 31b increases as the distance e increases. The greater the range in which the electric lines of force 71 spread, the wider the range in which the sensor unit 24, the sensor unit 24, and the first wiring 26 or the second wiring 28 can detect the external conductor 72. For example, the distance E between the second surface 22 b of the base material 22 and the outer conductor 72 when the sensor unit 24 starts to detect the outer conductor 72 is increased. That is, the sensitivity of the sensor unit 24 is improved.

図１０に示す例において、間隔ｃ，ｄ，ｅは、第１隙間Ｓ１の幅ａに等しい。第１隙間Ｓ１の幅ａを大きくすると、第１隙間Ｓ１がユーザーに視認され易くなる。このため、図１０に示す例においては、間隔ｃ，ｄ，ｅが制限され、この結果、センサ部２４の感度も制限される。 In the example shown in FIG. 10, the intervals c, d, e are equal to the width a of the first gap S1. Increasing the width a of the first gap S1 makes it easier for the user to visually recognize the first gap S1. For this reason, in the example shown in FIG. 10, the intervals c, d, and e are limited, and as a result, the sensitivity of the sensor unit 24 is also limited.

一方、図１１に示す例において、間隔ｃ，ｄ，ｅは、第１隙間Ｓ１の幅ａを二倍した値に第３線状部分５１の幅を加えたものとなる。図１１に示す例によれば、第１隙間Ｓ１の幅ａを維持しながら間隔ｃ，ｄ，ｅを大きくして、センサ部２４の感度を向上させることができる。例えば、センサ部２４が外部導体７２を検出し始める際の、基材２２の第２面２２ｂと外部導体７２との間の距離Ｅを、図１０に示す例の場合に比べて大きくすることができる。このことにより、例えば基材２２の厚みが大きい場合や、基材２２の第２面２２ｂ側に更に保護カバーなどが設けられる場合であっても、外部導体７２を適切に検出することができる。 On the other hand, in the example illustrated in FIG. 11, the intervals c, d, and e are obtained by adding the width of the third linear portion 51 to a value obtained by doubling the width a of the first gap S1. According to the example shown in FIG. 11, the intervals c, d, and e can be increased while maintaining the width a of the first gap S1, and the sensitivity of the sensor unit 24 can be improved. For example, the distance E between the second surface 22b of the base material 22 and the external conductor 72 when the sensor unit 24 starts to detect the external conductor 72 may be made larger than in the example shown in FIG. it can. Thereby, for example, even when the thickness of the base material 22 is large or when a protective cover or the like is further provided on the second surface 22b side of the base material 22, the external conductor 72 can be detected appropriately.

〔第３の実施の形態〕
以下、図１２を参照して、第２の実施の形態について説明する。第２の実施の形態は、第２配線が第１配線と同じ側で第２電極に接続されている点が異なるのみであり、他の構成は第１の実施の形態と略同一である。第２の実施の形態において、第１の実施の形態と同一部分には同一符号を付して詳細な説明は省略する。また、第１の実施の形態において得られる作用効果が本実施の形態においても得られることが明らかである場合、その説明を省略することもある。 [Third Embodiment]
Hereinafter, the second embodiment will be described with reference to FIG. The second embodiment is different only in that the second wiring is connected to the second electrode on the same side as the first wiring, and other configurations are substantially the same as those of the first embodiment.

Therefore, a capacitance proportional to the lengths of the opposing portions of the second wiring 28 and the first linear portion 31a is provided between the second electrode side portion 281 of the second wiring and the first linear portion 31a. The capacitor can be formed. Therefore, the capacitance of the sensor unit 24 can be further increased, and thereby the detection sensitivity of the sensor unit 24 can be further increased.

また、本実施の形態によれば、第２電極側部分２８１の側部２８３は、図１２に示すように、第１配線２６の側部２６３に対向する。この場合、第１配線２６と第２配線２８との間に、コンデンサを形成することができる。したがって、センサ部２４の静電容量をさらに増加させることができ、このことにより、センサ部２４の検出感度をさらに高めることができる。 Further, according to the present embodiment, the side portion 283 of the second electrode side portion 281 faces the side portion 263 of the first wiring 26 as shown in FIG. In this case, a capacitor can be formed between the first wiring 26 and the second wiring 28. Therefore, the capacitance of the sensor unit 24 can be further increased, and thereby the detection sensitivity of the sensor unit 24 can be further increased.

It arrange | positions between the parts 31a. The sensor unit 24 further includes a dummy electrode 50 that is not connected to either the first electrode 30 or the second electrode 40.

ダミー電極５０は、少なくとも第３線状部分５１を含む。第３線状部分５１は、図１３に示すように、第１線状部分３１の側部３１１と第２線状部分４１の側部４１１との間に位置する。また、第３線状部分５１は、第１配線２６の側部２６３と、第１配線２６と隣り合う第２配線２８の側部２８３と、の間に位置する。更に、第３線状部分５１は、第２配線２８の側部２８３と、第２配線２８と隣り合う第１線状部分３１ａの側部３１１と、の間に位置する。 The dummy electrode 50 includes at least a third linear portion 51. As shown in FIG. 13, the third linear portion 51 is located between the side portion 311 of the first linear portion 31 and the side portion 411 of the second linear portion 41. The third linear portion 51 is located between the side portion 263 of the first wiring 26 and the side portion 283 of the second wiring 28 adjacent to the first wiring 26. Further, the third linear portion 51 is located between the side portion 283 of the second wiring 28 and the side portion 311 of the first linear portion 31 a adjacent to the second wiring 28.

図１３において、符号ｆは、第２方向Ｄ２における、第２配線２８と、第２配線２８と隣り合う第１電極３０の第１線状部分３１ａと、の間の間隔を表す。また、符号ｇは、第２方向Ｄ２における、第１配線２６と第２配線２８との間の間隔を表す。本実施の形態によれば、第３線状部分５１を設けることにより、第１線状部分３１と第２線状部分４１との間の間隔ｃと共に、第２配線２８と第１線状部分３１ａとの間の間隔ｆ、及び、第１配線２６と第２配線２８との間の間隔ｇを拡大することができる。 In FIG. 13, a symbol f represents a distance between the second wiring 28 and the first linear portion 31 a of the first electrode 30 adjacent to the second wiring 28 in the second direction D2. The symbol g represents the interval between the first wiring 26 and the second wiring 28 in the second direction D2.

Thereby, a capacitor is also formed between the second wiring 28 and the first linear portion 31 a of the first electrode 30. By placing the dummy electrode 50 between the second wiring 28 and the first linear portion 31a, the interval f can be increased while maintaining the width a of the first gap S1. As a result, the sensitivity of the sensor unit 24 can be further improved.

また、第２電極側部分２８１の側部２８３は、図１３に示すように、第１配線２６の側部２６３に対向する。これにより、第１配線２６と第２配線２８との間にもコンデンサが形成される。このような第１配線２６と第２配線２８との間にダミー電極５０を置くことによって、第１隙間Ｓ１の幅ａを維持しながら間隔ｇを大きくすることができる。このことにより、センサ部２４の感度をさらに向上させることができる。 Further, the side portion 283 of the second electrode side portion 281 faces the side portion 263 of the first wiring 26 as shown in FIG. Thereby, a capacitor is also formed between the first wiring 26 and the second wiring 28. By placing the dummy electrode 50 between the first wiring 26 and the second wiring 28 as described above, the gap g can be increased while maintaining the width a of the first gap S1. As a result, the sensitivity of the sensor unit 24 can be further improved.
